Several years ago, two scientists announced that they had evidence of "cold fusion" in the laboratory, but further studies failed to replicate their findings, and it was later found that the original scientists had used sloppy methods. This highlights which of the following critical thinking principles? A. Few "truths" do not need to be tested.
B. All evidence is not equal in quality.
C. Authority or expertise does not make the claims of the authority or expert true.
D. Critical thinking requires an open mind.

B. All evidence is not equal in quality

Explanation:

The scenario that is being described in the question highlights the critical thinking principle that all evidence is not equal in quality. Just because the evidence is said to exist does not mean that it is of high quality or even of any value at all. Such as in this case, the scientists claimed that they had evidence of "cold fusion" but that evidence was useless due to their sloppy methods of recording all of their tests/findings.

dude the first thing it says is that copied answers will get a zero. plus it would take anyone on an incredibly long time to answer. ive seen 2 people asking the exact same question and their questions got taken down. i have the assignment too, and im in the progress of doing it. i suggest going to a more private website, because this is the first place teachers look.
